Answer:
1.) C. transport oxygen
Explanation:
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies ( inspiration, or inhalation ) and send carbon dioxide out ( called expiration, or exhalation ).
2.) D. pharynx
Explanation:
Pharynx-- is the muscle-lined space that connects the nose and mouth to the larynx and esophagus ( eating tube ).
3.) A. alveoli
Explanation:
Every few seconds, with each inhalation, air fills a large portion of the millions of alveoli. In a process called diffusion, oxygen moves from the alveoli to the blood through the capillaries ( tiny blood vessels ) lining the alveolar walls.
4.) A. Carbon dioxide
Explanation:
The role of the Respiratory System is to breathe in oxygen and breathe out carbon dioxide. This is known as respiration. The cells of the body use oxygen to perform function that keep us alive. The waste product created by the cells once they have performed these functions is carbon dioxide.
5.) B. diaphragm
Explanation:
As you breathe in, your diaphragm contracts and flattens out. This allows it to move down, so your lungs have more room to grow larger as they fill up with air. And the diaphragm isn't the only part that gives your lungs the room they need.
6.) B. taking a bath regularly to avoid infections
7.) B. larynx
Explanation:
The larynx, or voice box is the top part of the air-only pipe. It is located on the neck and performs several important in the body. The larynx is involved in swallowing, breathing, and voice production.
8.) B. diaphragm--air sacs ( lungs )-- trachea--nose
Explanation:
In order for the lungs to expel air the diaphragm relaxes, which pushes up on the lungs. The air then flows through the trachea then through the larynx and pharynx to the nasal cavity and oral cavity where it is expelled out of the body.
